Today I was diagnosed for kidney stones. Ultrasound reports said that I have 8mm stone in left kidney which is 9cm away from upj. Does this mean that stone is in urinary track? What are the chances to pass it? I have kidney stone problem from past 4 years even got endoscopic surgery done once and I had passed stones sized up to 5mm but not 8 mm. I dont wish to get operated again my stones are calcium oxilate. Please help.
